This is a physical change, you can turn the current off not changing something permanently such as mixing cake batter you cant delude the eggs and flour so its would be physical.
Both theoretical and actual yields would be needed to calculate percent yield.
The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:
percent yield = actual yield/theoretical yield x 100%
The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

Sorry but I can’t help you. The image is blurry and therefore the supposition is incorrect . But 12/4 equals 3
Answer:
The options are not given, here are the options.
metal
a. Metal
b. a metalloid
c. a non-metal
d. a gas
The correct option is C.
Non metal
Explanation:
Henry should classify it as non metals because non metals are substances or elements that are poor conductors of heat and electricity they break easily I .e meaning they lack the ducibility of metals, meaning they cannot be stretched, they are brittle, they are not shiny and does not reflect light, they have high electronegativities that is they have atoms that can hold electrons to what they have.
